Tommy John, Pitcher Whose Name Became Synonymous With UCL Surgery, Has Died

Tommy John, the left-handed pitcher whose longevity in the major leagues became inseparable from the surgical procedure that now bears his name, has died, as reported by Bryan Hoch for MLB.com.

John's legacy extends well beyond his own career on the mound. UCL reconstruction — colloquially known as Tommy John surgery — has since become one of the most common procedures in professional baseball, altering the career trajectories of pitchers at every level of the game. His willingness to undergo what was then an experimental operation, and his subsequent return to pitching, effectively opened a door that has since been walked through by a generation of arms.

The Los Angeles Dodgers, the organization with which John is associated in this report, have not issued a separate statement beyond what MLB.com has published.
